Electric Bike Size

Electric Bike Size: How to choose the correct size when planning to buy an Electric Bike?

Electric bike Size: One of the most important things while buying an electric bike is choosing the correct size. Wrong size can lead to uncomfortable journeys or even an injury. Riding a bike in wrong size just isn’t fun. Buying an electric bike is a big investment and you don’t want to buy it in wrong size! Making sure that the bike is in correct size before purchase is the best way to ensure the efficiency, longer use and overall enjoyment.

Ironically, this is one of the last things people think of. All those charts and numbers just seem to be boring. You may think, bike either fit me or it doesn’t. This approach may work out just fine when you are going to try in bike shops or bike rental places, but how can you pick the right size when trying to shop for electric bikes on-line?

Below you will find 6 answers that will help you to buy an electric bike.

Everything you need to know about the bike sizes whether you are planning to buy an Electric Mountain Bike, an Electric Road Bike, Hybrid Electric Bike or a Cruiser.

1. Find out Your Own Measurements

These three basic measurements are necessary to find out the right size for you
a) Measure Your leg inseam (from the crotch to your the ground)
b) Measure Your torso length (from the crotch to your sternum, the V-shaped curve below your neck)
c) Measure Your arm length (from the end of your collarbone to the middle of your closed fist)

2. What is the purpose you are planning to use Your Electric Bike for and where are you going to ride with it?

Are you a commuter or mountain biker? Going for a upright or aggressive ride? Sizes of the Cruisers, Mountain bikes, Road bikes or hybrid bikes are a bit different. Before you start trying to measure yourself, make sure you know the main use for the bike. But probably was the first thing You were thinking about, so this should be an easy part.

3. Frame Size of Your Electric Bike?

Frame size is most likely the most important aspect in bike sizing. Once you have chosen the frame size, there is no turning back from there. There are some good ways that you can use to find the right frame size.

First you should measure your inseam. Measuring your inseam can be done in many ways, but one of the easiest way is to grab a book. Once you’ve got a book, you’ll need to stand against a wall. Then, place the book in between your upper thighs so you are straddling it. Leave the book in place on the wall and measure from the top of the book to the floor. This measurement is your inseam. It’s generally a good idea to wear the shoes you’ll be cycling in most frequently as this will probably affect the measurement. Once you have the measurement, reference a sizing chart like the ones listed here:

Electric Road Bike Size:

Electric Mountain Bike Size:

Frames of the Electric mountain bikes are generally a bit smaller than road bike frames, to make them easier for you to handle on rough terrain. First it may feel odd and uncomfortable as you sit on a bike, but it’s a natural riding position. If you are able to put both feet on the ground while sitting on the seat, the bike is too small or the seat is too low, or both. Also, when sitting on the seat, your feet should be comfortable on the pedals and you should be able to reach the handlebars comfortably without either being scrunched too close together, or being stretched too far out as you lean forward to get them.

Hybrid Electric Bike Size:

Hybrids are typically used for commuting or leisure riding. They often incorporate the mountain electric bike styling, but with smoother and narrower tires. Or they look like a road bike but with flat handlebars. When choosing your hybrid bike, it’s best to consider whether you’ll be riding mainly on or off-road. This handy chart should show you the right size of hybrid bike you need based on your height. Measure your height accurately and check the manufacturer’s measurements too. Always make sure you’re able to stand over the frame with a minimum 2cm gap between you and the top tube.

Women’s Hybrid Electric Bike Size:

Women’s hybrids differ from male or unisex hybrids. They tend to be shorter in length with narrower handlebars and smaller frame sizes. In some cases they’ll have a step through frame where the top tube drops down, meeting the seat tube much lower. In some cases a male or unisex hybrid may suit you better.

Cruiser Electric Bike Size:

Cruiser bikes are measured in 2 different ways. Outside diameter of the tire. Most adult bikes have a 26″ diameter. The second type of measurement refers to the frame size from the crank to the house of the seat clamp (in other words along the seat post tube top to the bottom) this measurement is generally 19″ for men’s cruisers and 17″ for ladies bikes. This is a less universal measurement and varies depending on the manufacture.

Measuring tips

As you can see, you can alternatively use your height as the main measurement. It’s really up to you, but the inseam generally is more reliable.
Ideally, the next thing you want to do in terms of frame size is actually hop on the bike. This isn’t always possible, but if you can you’re checking that you can straddle the frame with your feet flat on the floor. If you have a traditional top tube that is parallel to the ground there should be about an inch or two of clearance.

As mentioned, Your inseam is the most often used measurement. Most electric bike size charts note the stand-over height. This is your inseam plus another 1-2 inches for comfortable clearance of that top tube. Some sources claim that road bikes require 1-2 inches clearance while mountain or commuter bikes need 2-4 inches. (If you’re using a bike with a step-through frame, then that measurement of reference doesn’t really work since the top tube is lowered.)

If there is no top tube, you can only sit on the seat. You should be able to touch the ground with your feet, but only on tippy-toes, and even then maybe on one side or the other.

Another formula is that of the top tube length. To figure out your ideal top tube length, do the following math:
(torso length + arm length) / 2 = x and x – 6 = top tube length

This will tell you in inches what the ideal distance would be between your seat and handlebars.

4. How to adjust the Saddle?

Saddle height is also very important. Too high or too low and you won’t bike as efficiently. To size this properly, take one of your feet and put it on the pedal at the bottom of the pedal stroke (it’s lowest point). There should be a slight bend in your knee. Go for about 80-85% of full extension. When you hop on the bike, your knees shouldn’t be coming up too much past the top tube. I’d recommend getting a quick release for your seat post because if anything moves on you it’s much easier to adjust.

You also want to make sure your saddle tilt is set properly. Generally, the saddle should be flat (parallel to the ground). For cruisers and commuter bikes you might want the saddle tilted back a very little bit for a more upright ride. The opposite is true of mountain bikes. Tilt your seat forward slightly for a more aggressive feel.

5. What to know about Upper Body Position

Your upper body position is very important. If this is off, you could end up with a backache and tired arms. You’ll want a slight bend in your arms on any bike. Your posture will be affected based on the type of bike you’re riding. Comfort is key here. If you hop on the bike and five minutes later you’re already hurting, that’s a problem. For electric mountain bikes and electric road bikes, you’ll have a more significant bend in the back because they are more aggressive rides. If it is a commuter or urban electric bike, you should be more upright, almost like you’re sitting in a chair.

6. Try the bike if possible, do the measurements and some basic math if buying on-line

Ultimately, finding a well fitting bike is like finding any well fitting clothes – only trying it on will really tell you how it fits. Bike sizing is an art not a science. Figuring out some basic math and having a few numbers for reference will certainly help get you in the right direction and it will even allow you to rule out easily identifiable too big or too small bikes when shopping on-line, but nothing will truly confirm that a bike is the right one for you until you take it for a spin. And bike fit can also be adjusted by moving the height of your seat or your handlebars. It’s all about experimenting with what feels right and comfortable to you, which is also something that might change over time as you get more confident on a bike and maybe even alter your riding style.

7. Conclusions

Find out the purpose of your rides. Once you’ve got all the necessary measurements, use provided charts to choose the right electric bike size values. Buy from the local store or on-line, made the proper adjustments (saddle and handle) and you’re all set to ride! Invest some time and make sure to get the proper measurements! It’s a little bit of work, but it will pay dividends in the long run when you’re biking more efficiently and having more fun doing it.
